Last time I checked, love doesn't actually have parameters.
I love life. I love myself. I love people. I love learning. I love knowledge.
I think that just about covers it.
What have I done to express my love? I guess that would depend on what exactly you want to know. I expressed my love to mother today. I expressed my love and compassion to others, so as to wake up them up from the dream world they seem to live in. I lovingly paid a pretty lady a compliment and was told I was charming(not that I believed her when she said it).
Is that a good enough answer to your questions? I hope so.
